Specification of Letters Patent.

Patented June 2, 1908.

Application filed July 23, 1907. Serial No. 385,154.

To all whom it may concern:

Be it known that we, NATHANIEL M.

'JONES and LEONARD B. BRYANT, of Bangor Log-Carriers-and StakesTherefor, of which the following is a specification.

This invention relates to carriers for transporting logs and otherelongated bodies of considerable bull: and weight, and may be embodiedin a carrier adapted to be drawn by draft animals, or in a carrier, suchas a platform car, adapted to run on rails.

The invention has for its object to provide a stake adapted to retain aload upon the carrier, and to be readily released from its operativeposition to release the load without being disconnected from thecarrier, our invention being embodied in a reinforcing member adaptedfor attachment to the carrier body,

and provided with a dog-engaging shoulder, and a stake pivoted to saidmember, and provided'with a pivoted dog adapted to engage said shoulder,the arrangement being such that the stake is adapted to swing downwardlyto an inoperative position below the carrier, and to swing upwardly toan operative position above the carrier, the dog and shoulder being soarranged that the dog when engaged with the shoulder acts as a strut tolock the stake in its operative position, and oppose outward movement ofthe stake, all as hereinafter more fully described.

Of the accompanying drawings, forminga part of this specification,Figurel represents a side elevation of a rocker adapted to be mounted on sledsor other supports, and forming part of a log-carrier, the said rockerbeing provided with stake-attachments, em-

bodying our invention, a portion of the rocker being shown in section.Fig. 2 represents an end elevation of the rocker and stake-attachmentshown in Fig. 1. Figs. 3 and 4 represent perspective views showing theparts of the stake-attachment detached from each other and from thecarrier.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, 12 represents a rocker which forms a part of anordinary log-carrier, such as is used in logging operations, the rockerbeing composed of a stout beam adapted to be mounted upon sleds ortrucks,

and constituting a part of a log-carrier, the

complete carrier comprising two similar rockers and their supports.

For convenience we hereinafter refer to the rocker 12 as a carrier, andit will be understood that this term is intended to include any supportfor a load of logs, such as the body of a fiat or platform car.

13 13 represent reinforcing members applied to the carrier 12, the saidmembers being at opposite sides of the log-supporting portion of thecarrier, and provided with downwardly projecting ears 14, which enterslots formed for their reception in the carrier. Between the ears 14,the member 13 is provided with a slot 15, the inner end 16 of whichconstitutes an abutment for a stake 17. The said stake is pivoted at 18to ears 14 14, the ears arrangement being such that when the stakeprojects upwardly, as shown by full lines in Fig. 1, it will bearagainst the abutment 16, the latter preventing the stake from swinginginwardly beyond a substantially vertical position. The stake is adapted,however, to swing outwardly in the slot, and to depend vertically fromthe carrier, or to stand at any intermediate angle, for use as a skid,to assist in loading logs on to the carrier. The reinforcing member 13is provided with a shoulder 19, which is opposed to the abutment 16 andis located at the outer end portion of the reinforcing member andoutside, or at the-outer side of the stake. 20 represents a dog, whichis pivoted at 21 to the stake, and projects outwardly from the stake andis adapted to engage the shoulder 19 when the stake comes to a bearingon the abutment 16, the location of the shoulder 19 outside the stakecausing the dog to act as a strut to oppose outward movement of thestake under the outward pressure of the load against it. The engagementof the dog with the shoulder 19 therefore locks the stake againstoutward movement, the dog being held in engagement with the shoulderwholly by the outward pressure of the load against the stake. Thereinforcing member, the stake and the dog are preferably composed ofmetal. The reinforcing member is securely attached to the carrier bybolts 25, aided by the engagement of the ears 14 with the slot formedfor their reception in the carrier. The dog is provided with ears orwings 23, the lower ends or faces of which are above theshoulder-engaging end of the dog, and are separated from the reinforcingplate by a space adapted to receive a crowbar or other instrument,whereby the dog may be pried upwardly to disengage it from the shoulder1-9. A very slight upward movement of the dog is suflicient for thispurpose. The pressure of the load against the stake throws the latteroutward when the dog is disengaged. Two wings 28 are referably providedso that two prying too s can be used simultaneously to raise the dogfrom engagement with the shoulder 19.

It will be seen that the dog 20 acting as a strut held by the load inengagement with the shoulder 19 located outside the stake is adapted tobe held in its operative or looking position wholly by the pressure ofthe load against the stake, no additional or special dog locking orholding means being required. It will also be seen that the reinforcingmember 13, made in a single part, furnishes a secure connection betweenthe stake and the body of the carrier, and also provides for the secureengagement of the dog with the carrier to hold the stake in itsoperative position, the reinforcing member sustaining all the wear dueto the swinging of the stake on its pivot, and to the engagement of thedog with the carrier. We do not limit ourselves to the employment of areinforcing member made in one piece, which includes the bearings forthe stake, as our invention may be embodied in any suitable structure,comprising a portable support having a stake abutment, and adog-engaging shoulder opposed to said abutment and located outside thestake, in combination with a stake pivoted to the support, and adaptedto bear against the abutment when in its operative position, and a dogpivoted to the stake, and adapted to en gage the said shoulder when thestake comes to a bearing on the abutment, the dog acting as a strutwhich is held in engagement with the shoulder wholly by the pressure ofthe load.

We claim 1. A stake attachment comprising a reinforcing member adaptedfor attachment to a supporting body, and provided with a stake abutment,and with a dog-engaging shoulder opposed to said abutment, and a stakepivoted to said member, and provided with a dog adapted to engage saidshoulder, and hold the stake against the abutment.

2. A stake attachment comprising a reinforcing member adapted forattachment to a supporting body, and provided with a slot,

the inner end of which forms a stake abutment, depending ears atopposite sides of the slot, and a shoulder opposed to said stop, a

stake pivoted to said ears at a point below the plate, and a dog pivotedto the stake and adapted to engage said shoulder and hold the stakeagainst the abutment;

3. A portable support having a stakeabutment, and a dog-engagingshoulder opposed to said abutment, a stake pivoted to the support, andadapted to bear against the abutment when in its operative position,,and a dog pivoted to the stake and adapted to engage said shoulder whenthe stake comes to a bearing on the abutment.

4. A portable support having a dog-engaging shoulder, a stake pivoted tothe support, and a dog pivoted to the stake, and adapted to engage theshoulder, said dog having a face,

separated from the support by a tool-receiving space, the shoulder beinglocated at the outer side of the stake, so that the dog acts as a strutto oppose outward movement of the stake.

5. A portable support having a slot extending inwardly from its outerface, said slot being open both at the top and bottom of the support, astake-abutment at the inner end of the slot, a dog-engaging should-eropposed to the abutment and located between the said abutment and outerface, a stake pivotally connected with the support within the slot, andadapted to bear on the abutment when in its operative position, and adog pivoted to the stake, and adapted to engage the shoulder and holdthe stake in its operative position, the stake being adapted to swingdownwardly in the slot from said position.

6. A portable support having a dog-engaging shoulder at its outer end, astake abutment at the inner side of said shoulder, a stake pivoted tothe support at a point below the shoulder and abutment, and adapted tooccupy a vertical position to support the load, and to be inclineddownwardly and outwardly from the support to act as a skid, and a dogpivoted to the stake and adapted to engage the shoulder and hold thestake against the abutment, the dog being at the outer side of the stakewhen the latter is in its vertical position, and at the under side ofthe stake when the latter is inclined to act as a skid.

In testimony whereof we have affixed our signatures, in presence of twowitnesses.
